When a force pushes or pulls the object, the object will move in the direction of the force. Force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball) or over a distance (such as a magnet or gravity)
Hello!
Yes, someone with an IQ score of 120 can be gifted.
An IQ score of 120 means that the individual is moderately gifted. Although this IQ doesn't qualify for gifted education programs, research shows that people with IQs of about 145-180 don't perform significantly better than people with 120s IQ in terms of success.
As an example, professor Dean Simonton from the University of California found that an optimum leader should have an IQ in the 120-125 range, so having an IQ of 120 would mean that the individual is gifted for leadership.
Have a nice day!
Answer:
![a = 0.65\ m/s^2](https://tex.z-dn.net/?f=a%20%3D%200.65%5C%20m%2Fs%5E2)
Explanation:
<u>Net Force</u>
There are four forces acting on the sled:
Its weight W directed down
The normal force N directed up
The applied force F directed left
The friction force, opposite to the motion, directed right.
The forces are shown in the free-body diagram of the figure below.
The body is in equilibrium in the vertical direction, thus:
N = W = m.g
N = 80 Kg . 9.8 ![m/s^2](https://tex.z-dn.net/?f=m%2Fs%5E2)
N = 784 Nw
In the horizontal direction, the sum of the force vectors is the net force:
Fn = F-Fr
It's assumed the left as positive.
The friction force is calculated as:
![Fr =\mu_k . N](https://tex.z-dn.net/?f=Fr%20%3D%5Cmu_k%20.%20N)
Fr =0.125*784 Nw
Fr = 98 Nw
According to Newton's second law, the net force is equal to the mass by the acceleration:
F-Fr=m.a
The acceleration can be calculated by solving for a:
![\displaystyle a=\frac{F-Fr}{m}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%3D%5Cfrac%7BF-Fr%7D%7Bm%7D)
![\displaystyle a=\frac{150-98}{80}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20a%3D%5Cfrac%7B150-98%7D%7B80%7D)
![\mathbf{a = 0.65\ m/s^2}](https://tex.z-dn.net/?f=%5Cmathbf%7Ba%20%3D%200.65%5C%20m%2Fs%5E2%7D)
